Best Cold Air Intake for 6.7 Cummins

We’ve reviewed the best cold air intake for 6.7 Cummins – October 2019

It’s no secret that the partnership between Cummins and RAM goes a long way. The former turns 100 this year and has been supplying a variety of engines to RAM for 30 years. The Cummins 6.7-litre Turbo Diesel engine is available for Dodge RAM 2500 and 3500 trucks, offers more power (up to 400 hp and 1000 lb-ft, if you’re looking at the top-spec 2019 model), and is also lighter and stronger.

While the partnership between Cummins and RAM is something fans are proud of — and rightfully so — your truck’s 6.7 can benefit from another successful partnership, especially if you’re looking for more punch from the motor. A cold-air intake, for instance, can be a match made in heaven. It won’t just let the engine take in more oxygen into the combustion chamber, it will also ensure that the Cummins 6.7 takes in more airflow overall — improving your truck’s overall power delivery.

You see with continued usage, the air filter gets clogged. And unless it’s cleaned on time, it starts affecting the engine both in terms of power delivery and efficiency. Prolonged use can eventually lead to irreparable damage and you’re left with a bill longer than the West Coast. So not only is choosing the right intake vital, servicing it periodically will benefit the way the truck drives and also strengthen its longevity.

Curated by the team at Mechanic Guides, here are some notable contenders for the best cold air intake for 6.7 Cummins available right now.

Popular Choice: S&B Filters 75-5068 Cold Air Intake For 2013-2018 Dodge Ram Cummins 6.7L (Oiled Cleanable, 8-ply Cotton Filter)

A popular choice among RAM owners, S&B Filters cold air intake for 6.7 Cummins promises 54.6 percent better airflow and an efficiency rating of 99.55 percent. It’s made of silicone parts that give it a longer life, whereas S&B claims the usage is less prone to engine error codes flashing on your truck’s display.

The fully enclosed airbox and the cotton cleanable air filter ensure the air is cleaner as well. In addition to that, the optional dual-inlet airflow (achieved by removing the dam from the gate arm), offers maximized performance. During harsh weather, it can be attached again to protect the engine. 

You can also opt for a dry extendable filter, which can be useful if you live in dusty conditions. This kind of filter is easy to clean with compressed air, something that’s not possible with the cotton filter. Having said that, cotton cleanable air filters are reusable, while dry extendable ones are not.

S&B Filters 75-5068 Cold Air Intake For 2013-2018 Dodge Ram Cummins 6.7L (Oiled Cleanable, 8-ply Cotton Filter)
  • 54.6% More Airflow & 99.55% Efficiency Rating. Tested To The Internationally Accepted ISO 5011 Standard
  • Designed To Avoid Check Engine Lights
  • Premium Silicone Parts Last Longer And Look Better
  • S&B utilizes robotics to precisely apply the correct amount of oil to your filter before it ships. Oil Amount: 72 Grams on Filter Element. Replacement Filter: KF-1037 & Filter Wrap: WF-1037
  • Street Legal in All US States, CARB Exempt ID: D-590-19
 

Widely available

The part is available for 2013-2018 models of both RAM 2500 and 3500 trucks, which is great. It’s also legal in all states and is CARB exempt. For those new to the term, CARB is short for California Air Resources Board. To legally buy and use the air filters in California, they have to be cleared from the agency. The easiest way you can find out if the product is street legal is with the CARB exempt EO number included with the product. If the cold air intake you’re buying for the Cummins 6.7 doesn’t have that, driving with that particular product in California is illegal.

Improved response

Take a look at S&B Cold Air Intake 6.7 Cummins Reviews, and you’ll find that owners experience a crisper throttle response, and the turbo/induction noise stands out a little more. The installation takes about 2 hours, and if you’re acquainted with your truck, it shouldn’t be a hassle for you.

Why do we like it?

A choice of filters, an improved airflow, and an improved response from the engine; what else would you want from a popular cold air intake. The ability to opt for a dual-flow inlet helps the engine breath even more. If you’re looking for a 6.7 Cummins cold air intake that gets the vote of owners, this has to be it.

  • Wide application

Best looking of the lot: Sinister Diesel Cold Air Intake for 2007.5-2012 Dodge Ram Cummins 6.7L

With its CNC Mandrel Bent Aluminum pipe finished in Sinister Blue (can also be specced in gray), the Sinister Diesel Cold Air Intake 6.7 Cummins does look good. It’s available for 2007.5-2012 RAM 2500 and 3500 trucks with the 6.7 Cummins engine and it’s plug-and-play. But if you have a 2013+ model, the company produces a different part, although that requires some engine tuning.

Sinister Diesel Cold Air Intake for 2007.5-2012 Dodge Ram Cummins 6.7L
  • Superior silicone couplers
  • CNC mandrel bent and engineered for maximum air flow
  • Construction - Aluminum
  • Sinister blue, providing a clean, distinctive look under your hood
 

Better build

The build is further strengthened by the use of aluminum and silicone couplings. Its use helps in a quicker turbo spool and an improved throttle response. While there’s no outright power gain, the increased responsiveness means the engine performs better in a variety of tasks. Sadly, its CARB certification is also pending so buying and using this one in California isn’t legal/recommended.

Why do we like it?

It looks good, makes the truck more responsive to the gas pedal, and you wouldn’t mind showing it off to your buddies, either. Did we say it looks good? On a serious note, the inclusion of an aluminium pipe and silicone couplings means the product is also meant to last longer.

Streamlined Choice: aFe Stage 2 Pro-5R Cold Air Intake System Dodge Ram 5.9L/6.7L Cummins 03-08

aFe makes a few types of cold air intakes for Cummins 6.7, and this one here is specced for RAM trucks with a model year of 2003-2009. 

The 6.7 Cummins intake produces an additional 14 HP, increases flow by 105 percent and comes with a washable conical air filter made from 100 percent polyurethane. For the RAM truck models we mentioned in the previous paragraph, it’s CARB-certified, so you can legally use it in California as well.

 

Why do we like it?

It’s one of the three cold air intakes mentioned here that adds substantial power thanks to the humongous increase in airflow. If you have a RAM truck (2003-09), this one deserves a chance because not only makes the engine breathe freely, it also ensures you can legally use it in California as well, while enjoying the increase in power.

Pros
  • Power gain
  • Carb-exempt

  • If you’re gonna pop the hood, this won’t stand out

Ease of Use: aFe 51-32413-E Cold Air Intake

For RAM trucks made from 2013-2018, the aFe Diesel Elite Magnum Force cold air intake offers improved airflow, a more vocal engine and turbo, and an easy-to-install setup. It’s priced lower than other systems, too. The aFe cold air intake 6.7 Cummins comes with a 3-layer performance air filter, which helps in increasing the flow by 48 percent.

Simple setup

The best bit about the unit is that its high-quality components don’t require modifications with the stock parts. The filter itself is reusable one, and aFe includes a 12 oz. cleaner spray along in the package. There’s no gain in power and torque and the unit isn’t CARB exempt.

Why do we like it?

If you’re looking for improved throttle response, better engine life, and an overall better sounding setup but don’t necessarily want to put any extra pressure on running gear or are happy with the engine’s power, then the Diesel Elite Magnum is an option worth considering.

Worth a second look: K&N 71-1557 Blackhawk Induction Air Intake System

Possibly the most widely known brand here, K&N also manufacturers an intake system for the equally popular Cummins 6.7 engined Ram trucks. The one you see here is the 71-1557 K&N Blackhawk, and it fits RAM 2500 and RAM 3500 models made between 2007-2009.

With an all-black paint for the whole system, you get a powder-coated aluminum tube, oil-free synthetic filter, and heat shield. The filter is said to have a long maintenance cycle — it can run up to 100,000 miles before requiring a clean-up.

  • ULTIMATE LONGEVITY: 10-Year/Million Mile Limited Warranty protects for the life of your vehicle.
  • GUARANTEED INCREASE IN HORSEPOWER: Dyno-tested with up to 50% more airflow than restrictive factory box air filter and intake tube
  • BETTER TOWING: Improves acceleration and uphill performance when towing by improving throttle response.
  • IMPROVED ENGINE SOUND: Hear the power under the hood.
  • WORLD CLASS PROTECTION: Pushing the limits of engine protection by protecting your engine from harmful contaminants
 

Power up

K&N says an estimated gain of 9.3 hp is achieved with the system, whereas the installation can take anywhere between 60 to 90 minutes. As for the filter type, the product we specified has a dry filter. There’s also one with an oiled filter and HDPE tube, (classified as a different model), and is said to achieve gains of up to 20 HP.

Why do we like this?

K&N is a fairly popular brand, and the wide variety of products available ensures that there’s something made for your truck. The model we chose here is a good mix of brand value, power increase, and low maintenance.

Pros
  • Increase in power

Most powerful upgrade: Injen EVO8002 Air Induction System

Injen’s Evolution air intake might have a very limited appeal (direct fit only for 2010-2012 RAM 2500 and 3500 models with 6.7 Cummins diesel engine) but with dyno-proven gains of 22 HP, it can’t be ignored. But what makes it even more desirable is the fact that neither the calibration nor the fit needs to be messed around with.

Not ready for California, yet

Although manufactured in California, the system isn’t CARB-exempt. It comes with polyethylene housing and intake tube, silicone couplers, stainless steel band clamps, and a dry air filter. The latter can be serviced/cleaned. With what Injen refers to as Clear-View badge, you can look at the filter’s health and clean it accordingly.

Why do we like it?

With the kind of power and torque upgrade it offers, the Injen wins our vote. With multiple patents applied for the EVO model, Injen is hugely proud of the product. And at a promised gain of roughly 22 HP, we bet you’d be too. In terms of power increment (and what’s advertised), it’s the best intake for 6.7 Cummins.

  • Massive power gains

Subtle Choice: Sinister Diesel Cold Air Intake for 2007.5-2012 Dodge Ram Cummins 6.7L (Gray)

If the above-mentioned Sinister Diesel Cold Air Intake (Blue) is a bit too gaudy in appearance, this slightly more subtle unit, finished in gray, might be the one for you. It can be fitted on Cummins 6.7 RAM 2500 and 3500 models (2007.5-2012) and offers an improved throttle response. It’s not CARB exempt so using one in California isn’t possible.

Why do we like it?

Even though it has a quieter appearance, the Sinister Diesel doesn’t lose anything compared to its blue-colored sibling. It offers the same sharp throttle response and a more (that stock) pronounced engine and turbo noise.

Pros
  • No gain in power

Banks 42255 Ram Air Intake System

Banks Power covers a variety of Cummins 6.7-engined Dodge Ram models (2007-09, 2010-12, and 2013-18) with its range of 6.7 Cummins Cold Air Intakes. The Banks 42255 Ram Air Intake System is made for the RAM 2500 and 3500 trucks made between 2013 and 2018. It’s said to offer more power and up to 66 percent improved airflow, resulting in an increment in your truck’s drivability.

CARB exempt

Banks Power doesn’t have a model for the 2019 Dodge Ram Cummins 6.7, but that might change in the near future, since the company is said to be testing on the model. On the bright side, Banks offers CARB-compliant models, and should you plan to buy/run your truck in California, they’ll send you a relevant sticker as well. Having said that, since there’s a variety of models, it’s best to check before investing if the particular model you’re looking at is CARB exempt. For instance, the version with the Dry Filter, for 2013-18 models is CARB exempt. And speaking of filters, the Banks 42255 Ram Air Intake comes with a oiled/cleanable filter.

Final thoughts

So what is the best cold air intake for 6.7 Cummins? Well, in terms of overall power delivery, the Injen Evolution takes the cake. The promised 22 HP increase is the highest here. On the other hand, if you’re looking for something with a wider range, then K&N is a solid second choice, given the number of models available. The aFe Cold Air Intake for 6.7 Cummins (Stage 2) offers an intermediate gain in power but is available for older trucks. If you’re satisfied with the power your truck makes, and are instead after a crisper throttle response, the S&B and Banks Power are two strong options you can explore. The Sinister Diesel models (grey & blue) are well-built and good to look at, whereas the aFe Diesel Elite Magnum Force makes for a great purchase as it also involves no further modifications for its fitment.

Apart from choosing the right intake depending on your needs, periodic service will not just benefit the way your Dodge RAM 2500 or 3500 drives but also strengthen its longevity. Another thing that must be noted is the choice of materials; the Sinister Diesel’s aluminum tube is bound to last longer than a plastic equivalent. The oil filter’s life is also dependent on where you drive. As mentioned above, if you’re in a dusty environment, a dry filter might make sense because you’d be able to clean it with pressurized air. That’s something a cotton cleanable filter won’t be able to handle.
